Description

Es handelt sich bei dem vorliegenden Verfahren um eine neuartige Fixierung des Filmstücks (Dia) in einem Dia­ rahmen.The present method is a novel fixation of the film piece (slide) in a slide frame.

Bei den üblichen Diarahmen wird das Filmstück entweder an den Rändern gefaßt, wobei durch die natürliche Wölbung des Films eine plane Lage und dadurch eine randscharfe Projektion ausgeschlossen ist (glaslose Rahmen), oder das Filmstück wird zwischen zwei Glasplättchen geführt, wobei Newton'sche Ringe und Wasserflecken sichtbar in Erscheinung treten (Glasrahmen).With the usual slide frames, the film piece is either framed at the edges, whereby by the natural curvature of the film a flat position and therefore a sharp edge Projection is excluded (glassless frame), or the film is passed between two glass plates, whereby Newton 's rings and water spots are visible in Appear appearance (glass frame).

Bei dem vorliegenden Verfahren wird die Planlage des Filmstücks erreicht, indem dieses - Emulsionsseite nach oben - auf eine durchsichtige Trägerplatte geklebt wird. Dadurch wird eine absolute Planlage des Filmstücks er­ reicht, ohne daß die Emulsionsseite mit einer Glasplatte in Berührung kommt. Die Trägerplatte wird dann in einem Diarahmen befestigt. (Fig. 1).In the present process, the flatness of the film piece is achieved by gluing it - emulsion side up - to a transparent carrier plate. As a result, an absolute flatness of the film piece is sufficient without the emulsion side coming into contact with a glass plate. The carrier plate is then attached in a slide frame. ( Fig. 1).

Die Verklebung erfolgt entweder:The gluing is done either:

  • a) mit Flüssigklebstoff, der durch Andruck des Filmstücks luftblasenfrei zwischen Filmstück und Trägerplatte verteilt wird.a) with liquid adhesive, which by pressing the Film piece free of air bubbles between film piece and carrier plate is distributed.
  • b) mittels einer Adhäsionskleberschicht, die bereits bei der Herstellung auf die Filmträgerplatte auf­ gebracht wird.b) using an adhesive adhesive layer that already during production on the film carrier plate brought.

Geringe Filmmengen werden manuell auf einzelne Träger­ platten geklebt (Fig. 1 und Fig. 3) und anschließend im Diarahmen (Fig. 4) befestigt.Small amounts of film are manually glued to individual carrier plates ( Fig. 1 and Fig. 3) and then attached to the slide frame ( Fig. 4).

Größere Filmmengen werden kontinuierlich auf einen end­ losen Träger geklebt und im Anschluß bildgerecht in Teil­ stücke geschnitten (Fig. 2).Larger amounts of film are continuously glued to an endless support and then cut into pieces according to the image ( Fig. 2).

Bei der Trägerplatte nach Fig. 3 ist eine umlaufende Rinne zu beachten, die die Aufnahme des überschüssigen Klebers ermöglicht, so daß die Verunreinigung der Emulsion durch den Kleber ausgeschlossen ist. Zwei Kanten an der oberen und unteren Seite der Trägerplatte ermöglichen eine genaue horizontale Ausrichtung des Filmstücks.In the carrier plate according to FIG. 3, a circumferential channel is to be observed, which enables the excess adhesive to be absorbed, so that the emulsion is not contaminated by the adhesive. Two edges on the upper and lower side of the carrier plate allow an exact horizontal alignment of the film piece.
